I agree the official WHW is a poorly designed archetype that shoves a grappler build onto a 1/2 BAB chassis that was possibly never intended for a serious PC.
As for the homebrews you provided:
There's an extra space in that first link is causing it to be broken. But once I was able to examine it, I was pleased with what I saw. It does a decent job of mixing the base witch with a bit a monk and its own natural flavor. She's not a great frontliner and her damage will quickly be outpaced by true DPS, but able to toss out an occasional spell of hex to help. It sacrifices a lot of its power as a spellcaster to gain the ability to become decent at grappling. Going to have to be very careful about spell selection with Magus advancement in spells. But if your GM rules hair can be used to deliver touch spells, that can be made up for. Considerably more powerful than the official WHW, but I think it's still a bit underpowered compared to the base class but that's actually the goal with designing most archetypes.
For WHW2, it's a mess. With spells, it gets the worse aspects of both Magus and Sorcerer as you combine few known spells with even fewer spells per day. The awkward cramming of abilities stolen from other classes as options are mediocre attempts to cover for the very limited abilities of this version. This version peaks at 5th level before becoming and natural attack rules make Combat Reflexes a required feat.
